When onboarding a new accounting client, organization and accuracy are key. A well-prepared new accounting client checklist ensures that accountants gather all necessary information, set up systems correctly, and deliver seamless service from day one.

Whether you are a CPA firm, an accounting outsourcing company, or a small business accountant, having a structured accounting new client checklist helps avoid confusion, data gaps, and compliance issues.

At OBG Outsourcing, we help CPA firms and small businesses streamline the onboarding process using a proven checklist approach to ensure smooth transitions and error-free accounting setup.

Why You Need a New Accounting Client Checklist

Starting work with a new client involves collecting a lot of financial and legal information. Without a checklist, it is easy to miss critical documents or setup steps.

A new accounting client checklist helps with

Ensuring accurate data migration from old books

Setting up accounting software correctly

Confirming compliance with tax laws and deadlines

Avoiding miscommunication with client

Delivering faster and more efficient services
 

This checklist saves time, improves accuracy, and creates a professional impression with clients.

Essential Steps in an Accounting New Client Checklist

1. Gather Basic Client Information

Start by collecting essential business details such as

Legal business name and entity type

Industry and primary operations

Business address, contact details, and EIN

Accounting period and financial year-end

 

2. Obtain Previous Accounting Records

Request access to past accounting data to maintain continuity. This includes

Prior year financial statements

General ledger reports

Trial balance

Chart of accounts

Bank reconciliation statements

 

3. Collect Tax Information

For tax compliance, gather

Employer Identification Number (EIN)

Previous tax returns (federal and state)

Sales tax registration details
 

• Payroll tax filings and reports
  
   

4. Review Accounting Software and Access

Ask which software the client currently uses (QuickBooks, Xero, Zoho, or Tally). Confirm access credentials and determine whether you will continue using the same system or migrate to a new one.

At OBG Outsourcing, our experts handle migration and cleanup for QuickBooks Online, Xero, and Zoho to ensure your financial data is accurate and up to date.

5. Review Bank and Credit Card Accounts

Request access to all business bank accounts and credit card statements. This helps in verifying balances and preparing for reconciliations.

6. Review Payroll Information

Collect payroll data such as

Employee lists

Payroll schedules

Tax deduction details

Year-to-date payroll summaries

7. Review Accounts Payable and Receivable

Request an updated list of

Customer invoices and outstanding balances

Vendor bills and unpaid obligations
 

This ensures accurate tracking of cash inflow and outflow during transition.

8. Set Up Communication and Reporting Protocols

Define how frequently you will provide financial reports and how communication will take place (email, Zoom, or project management software).

9. Confirm Tax Deadlines and Filings

Review all upcoming tax due dates, filing obligations, and payment schedules to prevent missed deadlines or penalties.
